IMPROVEMENT IN HYDROMETERS.

Spccitication forming part of Letters Patent No. 58,913, datcd October 16, 1966.

To all wiz/0m 'it may concern:

Be it known that I, G. TAGLIABUE, ot' 298 Pearl street, in the city, county, and State of New York,have invented a new and Improved Hydrometer; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawin g, formin g a part of this specification.

The drawing represents a longitndinal central section of this invention.

This invention consists in a hydrometer which has a lump of metal or other suitable material secured in its main bulb, in such a manner that said lump will firmly adhere to the inner surface of the glass, and the secondary bnlb used in ordinary hydrometers for the purpose of holding shot or mercury can be dispensed with. The length of the bulb is thereby` materially (liminished, and an additional space is obtained for the scale without increasing the aggregnte length of the instrument.

A represents a hydrometer, made of glass or any other suitable material. In the bulb a of this hydrometer a lamp, b, of metal or other suitable material is firnily secured, and the additional bull) or compartment, which in ordinary hydroineters servcs to confine the shot or mercnry, can be dispensed with.

The luinp b is made of metal, or an alloy of metals, which will fnse at a low temperature, and if the metal is placed in the bnlb and the bnlb is heated sutliciently high, said metal will melt and adhcre to the glass or other material from which the hydromctcr is made.

By dispensing with the additional bnlb or compartment, I am enabled to increase the length of the scale without producing an increase in the aggregate length of the entire instrument.

My instruments can be paeked np in a smaller coinpass than instruments of the ordinary construction, and a less depth of liquid isireqnired in measnring than With an ordinary hydrometer.

What Iclaini as new, and desire to secure by Letters Patent, is-

A hydrometer having a lamp of metal or other suitable material firmly secnrcd to the inner surface of the bnlb, snbstantially as and for the purpose described.
